"Riverdale" showrunner Roberto Aguirre-Sacasa brings a new iteration of "Sabrina" to Netflix this October.

Sabrina the teenage witch is back, but this is not the Melissa Joan Hart version from your childhood. Netflix has debuted the first look photos from its upcoming series “The Chilling Adventures of Sabrina,” starring “Mad Men” breakout Kiernan Shipka in the title role. The series puts a darker spin on the “Sabrina” comic books and comes from “Riverdale” showrunner Roberto Aguirre-Sacasa.

“The Chilling Adventures of Sabrina” follows the titular half-human half-witch as she battles the forces of evil threatening her world, all while deciding whether she wants the life of a witch or the life of a human. The supporting cast includes Miranda Otto, Lucy Davis, Ross Lynch, Michelle Gomez, and Chance Perdomo. The series marks Shipka’s first regular television role since starring as Sally Draper on “Mad Men.”
